To aZZ wwm it may concern.'

Be 1t known that we, JOHN JANUcHowsKY and HEINRICH ALBERT, citizens of the 'United States of America and residents of the city of St. Louis and tate of Missouri, have invented certain new and useful Improvements in Mechanism for Applying Bottle-Caps, of which the following 1s a lll() capping mechanism that will fit the cap per' specification.

rlhe primary object of this invention is Lto provide an improved mechanism for drawing and fitting closure caps over and around the necks of bottles.

Another object is to provide an improved mechanism for capping bottles that does not crimp the depending edge of the cap,

but in lieu thereof draws and smooths ,the

depending edge of the caps to the contour of the beaded edge of the bottle neck.

A further object is to provide a bottle fectly to the contour of the beaded neck of kthe bottle' both inside and outside thereof, thereby providing a perfect seal to the contents' of the bottle.

A still further object is to Vprovide a bot- 'tle capping mechanism that will produce a drawingl eect in opposite directions to the cap during the bottle capping operation. Other and further objects will appear in the specification and be specifically pointed out in the appended claims, reference beingI had to the accompanying drawings exemplifying the invention, and in which,

Figure 1 is a sectional view of this im proved device showing the parts in an inactive position, parts thereof being shown in full lines.

Fig. 2 is af'sectional view, similar to Fig. 1, but showing the device in an operative position.

Fig. 3 is a horizontal section taken on the line l[l[l[-Il[I, Fig. 1.l

Fig. 4 is a horizontal section taken on the line 11T-FV, Fig. 1.

Fig. 5 -is a horizontal section taken on the line V-`V, Fig. 1, the bottle cap being removed.

Fig. 6 is an inverted horizontal sectional view reducedy in size, and taken on the line Vll-Vl, Fig. 2.

Referring to the drawings: 1 [designates a s indle which has secured at one end thereofjhy a screw 2, a holder 3, said holder being edge of said groove terminates in constructed in two parts, the lower-portion thereof being in the form ofta nut 4. Said nut is secured to the upper portion 5 by the threads 6. Formed in the upper part 5 of( the holder 3 isa recess 7, the bottom of the side Wall 8 ofsaid recess having an inverted annular groove 9 formed therein.

Formed in the nut 4 is an annular shoulder 10, said shoulder having an annular groove 11 formed therein, said groove 11 being di-y rectly opposite to the inverted groove 9 formed in the upper portion 5 of the holder 3 when the nut t is secured to said upper portion 5. f v

Formed in the nut 4 is a bottle cap receiving chamber 12, said chamber having downwardly and inwardly inclined walls 13..

Formed in said nut, beneath said chamber, is a horizontally arranged cap receiving ledge 14. Formed in the side wall of said nut is a cap receiving opening 15, said opening communicating with the cap receiving chamber 12.

Arranged concentrically around the cap receiving chamber 12 is a series of wedge shaped members 16, each of said members 16 having a pivotalvportion 17 located apd v v proximately midway thereof. Each of s.

'pivotal portions is pivotally mounted in the grooves 9 and 11. Eachf the members 16 has an inwardly extending portion 18 formed on the upper end thereof, the lower end of each of said members 16 being formed in the cap engaging portions 19. rllhese ymembers 16, whenl in their concentric arrangement, have the1r side surfaces 1n engagement with each other.

Reciprocably mounted in the center of the members 16 is a bottle cap engaging plunger 20, said plunger having-a retaining flange 21, Which normally rests on the portions 18 .of the members 16, and an engaging shoulu the openingl, the lower depending edge of said cap resting on the cap receiving ledge 14 of the cap receiving chamber 12. This f will put the bottle cap in a position directly over the neck of the bottle.

When the platform 27 carrying the bottle 26, is elevated by means not shown, the cap 29 will concentrically engage the neck 28 as the bottle is moved upwardly. As the bottle still continues to move, it will carry the cap 29 upwardly, and the cap will engage against the under side of the shoulder 22 of the plunger 2O and iit into concentric relation wlth the annular depending flange 25. The plunger 20 will then be carried on upwardly, and the shoulder 22 thereof will engage vthe under side of the portions 18 of the members ,16. This action will cause the "-members 16 to rock on their pivotal'portions 17. The portions 19 of said members will be moved inwardly so that said portions wille'ngage against the depending flange 30 the portions 18 @f the members 16. Therefore, the top of the beaded edge 3l of the bottle will impress the cap 29 into the annular groove 23 formed' in the plunger 20, and the depending portion 24 of the plunger will cause a depression 32 to be formed 1n the 4top of the bottle cap. This pressing action, which is given to the top of the cap is done simultaneously with the inward bending of the liange 30 Vof the vcap in and around the outside of the beaded edge 31 of the bottle by the action of the portions 19 of the members 16.

It will, therefore, be seen that a drawing action is given to the ca 29 in opposite diwill ride away from the members 16, and the plunger 20 will ride on the bottle cap until the retaining iange 21 of the plunger will engage the extending portions 18 of the members 16. The plunger 2O and members 16 then being in their normal positions are ready for operation on another bottle cap.

With this improved construction, it is not necessary to have any resilient pressure applied to the top of the plunger, as the plunger will move downwardly of its own weight. If any of the members 16 fail to fall back in their normal positions, the weight of the plunger on the extending portions 18 of said members will cause them to be returned to their normal positions.

In the type of bottle capping devices now in use, the depending iange of the cap is merely pressed inwardly around the beaded edge of the bottle neck and crimped, and the sealing point ef contact of the cap with the bottle is merely around the top of the neck of the bottle. With this improved device, the sealing point of contact of the cap with the bottle is inside of the mouth of the bottle, all around the top of the bottle neck, and approximately all around the outside of the beaded edge ofthe bottle.

What we claim is:

1. In a bottle capping machine, a holder rigidly held against vertical movement, a series of radially arranged cap pressing members pivotally mounted in said holder, and a 'gravity actuated plunger supported and guided by said members mounted in said holder for actuating said members, said plunger being self-adjusting relative to centralizing itse f with said members.

`2. In a bottle capping machine, a holder having a chamber formed therein, a plunger located in -said chamber, a series of pivotally mounted cap pressing members radially arranged around said plunger, an inwardly extending portion formed on each of said members, a fiange formed on said plunger for engagement with the under side of said inwardly extending portions, and another iiange formed on said plunger for engagement with the top surface of said extended portions, said members providing guiding and supporting means for said plunger.

'3. In a bottle capping machine, a holder rigidly held against vertical movement, a series of radially arranged cap pressing members pivotally mounted in said holder, and a gravity actuated lunger su ported by said members mountedp in said ho der for actuating said members, said plunger by its own weight adapted to adjust said members rela- 65 AS the platform 27 is lowered, the bottle having a chamber formed therein, a plu- 13o rnlity of circularly arranged cap pressing members swingingly mounted in said chamber, an inwardly extending portion formed on each of said members, a lunger loosely mounted axially in said mem ers, lsaid members providing guiding means for said plunger, said members and plunger being self `adjustable relative to concentric displacement of each other.
